Don't ask how I know. But we worked on a car
with the same issue, only worse. The problem is the brackets are alot thicker then the stock frame rail material. And when you weld it in it needs more heat on the thicker material to make it actually penetrate the thicker stuff. Those parts are actually designed to be bolted in and one of my customers who has an engineering masters degree and a degree in welding inspection looked at the car here at the shop and said it might not have broken had we just bolted it in. CRAZY?? So on said car we just plated the outside frame rails with 1/8inch plate to spread the load over more of the rail.
Let me see if I have some pictures
